ACETYLENE-GAS GENERATOR.

SPECIFIGATIONforming part of Letters Patent N0. 74:9,75'7, dated January 19, 1904.

Application filed April 3, 1903.

T0 aZZ whom it may concern:

Be it known that I, ORION K. STUART, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Acetylene-Gas Apparatus; and Ido declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to apparatus in the use of which acetylene gas may be produced and stored while being distributed for consumption, and the invention has particular reference to apparatus of the above-mentioned character especially adapted for use on locomotives in connection with headlights, as well as for use in supplying buildings with gas.

The object of the invention is to improve the construction of acetylene-gas apparatus in order to attain simplicity and economy in manufacture of the apparatus, and particularly to providecompact self-contained apparatus that may be adapted to be used on moving vehicles, such as locomotives.

My invention consists in a supporting vessel adapted to be secured against displacement and provided with tension devices, a gas-holder in the supporting vessel provided with cables extending through the tension devices, an annular weight and guide combined connected to the cables and extending about the gasholder within the supporting vessel, and a carbid-holder supported by the gas-holder therein, and the invention consists also in the novel parts and in the combination and arrangement of parts, as hereinafter particularly described, and pointed out in the appended claims.

Referring to the drawings, Figure l represents an elevation of the apparatus, showing the gas-holder somewhat elevated as when in use, a portion ofthe supporting vessel being broken out to disclose the Weight and the lower portion of the holder; Fig. 2, a central vertical sectional view showing the several parts in the pos1t1ons they would occupy when not operat ng; Fig. 3, a perspectlve view of the annu- Serial No. 150,862. (1% model.)

lar weight and guide; Fig. 4, a top plan of the apparatus with the cables omitted; Fig. 5, a central vertical sectional view of the carbid-holder; Fig. 6, adiagrammatic figure illustrating the course of a cable through atension device; and Fig. 7, a horizontal sectional view taken in a plane above the carbid-holder through the gas-holder, showing a top plan of the carbid-holder and its supporting devices.

In the several figures of the drawings similar reference characters indicate corresponding parts.

My apparatus is supported entirely and partly contained in the supporting vessel A, which is preferably metallic and is designed to hold water or similar liquid as a compound with which the carbid is to be placed in contact, the vessel having a flat bottom a and no are connected thereto to cooperate with the cables above referred to. As at present informed, I prefer as such devices a suitable number of sheaves arranged in the following manner: Four housings O C O C are secured to the top of the sides of the vessel A, extending somewhat above the same and arranged at four points equidistant apart. In each housing a lower inner sheave D and an upper outer sheave E are mounted, the lower sheave D being situated so as to act as a guideroller for the gas-holder, and the sheave E being situated in a plane beyond the outer side of the vessel and preferably in a plane higher than the sheave D.

The gas-holder F is metallic and has a top at and no bottom and is substantially the same height as the vessel A, but of somewhat less diameter, so that a suitable annular space is provided between the gas-holder and the wall of the vessel A. Four arms G G G G are suitably secured to the top d of the gas-holder,

either by means of a common base 0 or independently, the latter being preferable in the larger sizes. These arms may be serviceable as handles whereby to lift the holder from the vessel A; but in the larger sizes of apparatus the holder F is provided with an eyebolt c, with which lifting-tackle may be connected. Each arm, as G, has an aperturefat its end. The holder F is provided with a stop-cock H at the top thereof. Hooks I are inserted in the apertures f, and cables J are attached to the hooks, one cable to each hook extending therefrom over and under a sheave E, thence over a sheave D and down the outer side-of the holderF within the vesselAnearly to the bottom thereof, when the holder is down to the bottom of the vessel. A combined annular weight and guide K, having a beveled inner edge g, extends about the holder F within the vessel A and is attached to the lower ends of the four cables, as by means of eyebolts h, secured to the weight. Thus the weight is operatively connected with the gasholder and, moving therewith, acts as a guide for the lower end thereof in connection with the vessel A, while the upper portion of the holder is guided by means of the sheaves D, the sheaves D andE acting as tension devices for the cables when they move upwardly, and it is obvious that the sheaves Emay be mounted adjustably, if desired, so that the tension may be varied in degree. It will be observed that the four arms are arranged at right angles and have their ends opposite to the tension devices.

The gas-holder F is provided at the middle portion of the interior thereof with an annular ledge L, extending inwardly from the wall thereof, for supporting the carbid-holder N, which is provided with a suitable number of supporting spring-arms 0, having bearingelbows 1; normally resting on the ledge and provided with fingers 1', extending below the ledge. The holderN is open at its top and has vertical rows of perforations k and a horizontal row of perforations Z near its bottom, the latter having perforations m therein. Within the holder N is a basket P, composed of wire-netting, cup shape like the holder N and resting on the bottom of the latter, the basket being designed to directly hold the carbid and permit the water to gain free access thereto. Within thebasket is a suitable number of plate partitionsQ to prevent packing of the carbid, the larger baskets having the greater number of partitions.

A- flexible distributing-conduit M is connected to the cock H and may be either rubber or metallic.

In practical use the vessel A is to be supplied with water or other suitable liquid, which may extendabove the central part of the vessel. The weightK should be suitably held within the upper end of the vessel A, which may be accomplished by means of one or more of the cables J, which may be connected to any suitable support above the vessel. The gas-holder F should be elevated. Then the basket P, supplied with carbid or similar substance, is to be inserted into the holder N, and the latter, with the basket, in

will cause the holder F to rise, the movement being graduated by means of the tension devices cooperating with the cables, and should excessive pressure be developed any excess in volume desired may escape harmlessly from the lower end of the gas-holder through the liquid seal and pass out at the top of the vessel A. As the carbid will be lifted out of the liquid by the gas acting against the holder F, generationof gas will cease until the gas may be drawn off, when the holder and carbid can descend, so that the latter will again be in contact with the liquid, when more gas will form and the above-described operation be repeated, the required production of gas thus being automatic.

Having thus described my invention, what I claim as new is 1. Gas apparatus including a supporting vessel, a gas-holder in the supporting vessel, a carbid-holder in the gas-holder, an annular combined weight and guide extending about the lower portion of the gas-holder within the supporting vessel, and cables connected with the gas-holder and also with the combined weight and guide.
